Application led April 3, 1918. Serial No. 226,404.

To all whom 'it may concern.'

Be it known that I, LUTHER L. KNoX,-a resident of Bellevue, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Hollow Water-Cooled Structures, of which thefollowing is a full, clear, and exact'de-` scription, reference beinghad to the accompanying drawings, forming part of i this specification,in which Figure 1 is a plan view, partly brokeirfl away, of a structureembodying4 my inven.k tion, and

Figs. 2 and 3 are sectional views taken on the lin'es II-II and III-III,respectively, of Fig. 1.

My inventlon has relation to hollow water, cooled structures formed ofsheet metal and capable-of use or the like.

The object of my invention is to provide a structure of thischaracterwhich can; be

for floors, bulk-heads, shields,

readily made from sheet metal in relativelyV which Awill possess the`necespreferred embodiment thereof, and which 'will now be described, itbeing premised,

. however, that my invention is not limited to vthe particular structureshown and described, but that various changes ycan be made thereinwithin the spirit and scope of the appended claims. v

In these drawings, which illustrate the 'application of j my lnventionto a structure capable of being used as awater cooled floor; thenumerals -2 and 3 designate the two plate or sheet members of whichvthebody of the structure is composed. `The upper member 2 has .its edgeportions flanged downwardly. as indicated at 4, to form the side wallsof the structure, these wall forming anges being preferably welded tothe edges of the bottom member 3, as indicated at 5. The structure isshown as having an internal bracing and reinforcing system which .isgenerally similar to that described and claimed in my Patent No.1,168,648 of Januaryv 18, 1916, 6 designating the internal strips havingspaced edge portions which are welded to the bottom plate 3. Instead,however, of making the -overlapping projections welded to the upperplate 2 of strip form, they consist of separate spaced projections 7 orlug members. It will be noted that the strips 6 have spaced projectionsat both edges, those opposite the welded edges bearing against the otherplate member. Also that the-lug members 7 are staggered with respect tothe projections on said strips, are shorter than the width ofthe strips,and are narrower than the spaces between the projections on the strips.This leaves vspaces through which water' passes "through the strips,thereby reducing heat nduction through the spacers and also giving freerwater circulation throughout the structure. 8 designates the key memberswhich-engage registering apertures in thestrips or together.

projections to tie the partsl 9 designates a water inletpipe whichentersone end of the structure at or near "thaceiter thereof, and ispreferably car- -yried through to a point near theopposite fend where itis 'provided with a discharge T 10. Thewater, as it is heated, finds itsway. back tothe opposite end portion of the structurevwhere it escapesby meansof the outlet connection 11.- If desired, the upper member 2 maybe inclined with respect to the lower member 3, so as to give the oor aninclined surface, as shown in Fig.A 2.

To receive the pipe 9 the key members 8 are formed in separate sectionsinserted on opposite sides of the structure.` I a It will be understoodthat any desired number of the unit structures shown may be placed sideby side in one or more rows to form a floor, bulk-head, or the'like; andthat the size and shape of the units may be varied according to thenecessity of the particular case.

I claim: Y

1. A' hollow water cooled sheet metal structure,- comprisin separatedplate members, a plurality o internal spacing and bracing strips eachAof which has separated edge projections welded to the inner surface ofone of the late members, and a plurality of lug-mem ers welded to theinner surface of the other plate member and over- -width than the spacesbetween adjacent `edge projections whereby whater circulating spaces ricare provided between said projections, substantially as described.

2. A hollow water cooled sheet metal structure, comprising separatedplate mem- .bers one of said members having a )luralit of spacing andbrat-i110' strips welded thereto, and the other member having a seriesof spaced projections welded thereto, said projections overlapping saidstrips, key1 members inserted through the registering openings in saidprojections and strlps, some of said key members being inserted in oneedge of the structure and others from the opposite edge of thestructure, and a Water inlet pipe extending between the adjacent innerends of the two sets of key members; substantially as described.

v3. A hollow Water cooled sheet metal mennen structure, comp'risinseparated plate memthe inner surface of the other plate member andoverlapping said strips, said lug members being staggered with respectto the projections of the strips, and key members en- I gaging saidstrips and lug members, substantially as described.

In testimony whereof, I have hereunto set my hand.
